A toolkit for building high-level compound widgets in Python using the Tkinter module. It contains a set of flexible and extensible megawidgets, including notebooks, comboboxes, selection widgets, paned widgets, scrolled widgets and dialog windows.
Python megawidgets is Python 3 compatible through the Pmw 2 download. Pmw 1 is destined for Python 2. Both are now accessible through the new pypi compatible package (credits for which go to Andy Robinson and the team at ReportLab).
Looks very promising, but am unable to use as I can't locate pmw file - getting import error of "no module pmw found" using python 2.7.13 on ubuntu 14.04lts.
